REVOLVING FIRE-ARM.

EPBCEEICATIQN forming part of Letters Patent No. 318,315, dated May 19, 1885.

Application tiled March Q3, lb.

To @ZZ wir/0711, t may concern,.-

Be it known that I, DEXTER SMITH, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Revolving Fire-Amis, ot' which the following is a specification.

This invention relates to improvements in revolving tire-arms, and pertains to the ejectoroperating mechanism ot'suoh arms, the object being to provide improved devices connected with and operating by the action ofthe frame and barrel joint for operating the shell-ej eetor, said improved devices embodying moans for preventing` the operation ofthe ejectorat will.

In the drawings forming part of this specification, Figure f is a side elevation, partly in section, of a tire-arm embodying my improvements,and showing projected therefrom one of Fig. 2 :is a side elevation oft-he barrel detached from the frame, the frame joint, and a view in perspective of the extractor-pawl and its nut and spring. Fig. 3 is a reverse side view ofthe frame-joint from that shown in Figs. l and 2.

In the drawings, Aiudicates that part of the pistol-frame extending under the cylinder B, and having the exterior cheek-pieces, a a', of the frame and barrel joint. Oneofsaid cheekpieces, a, has an angular slot, d, through it, opening quite to the side of thejoint part c of the barrel. (See Fig. 2.) The exterior cut of said slot is from 2 to 8, abridge, 7, being formed across it between 6 and 8, and at the latter point a hole is made quite through the part A, just below the opening, between the cheekpieces c a, said hole being counterbored from the opposite side to provide a shoulder, against which the end of the coil-spring m rests when the parts are assembled in working position. The joint part c of the barrel is provided with a curved slot, l0,through it, and between the joint parts c c is placed the armed disk o, having the curved slots e c' through it and the arm Said disk is hung on the joint-pin of the arm, and occupies operativelytheposition shown in Fig. l, said arm o extending to and engaging with the end of the extractor-stem o, and said disk is caused to rotate between the parts c c and drive the stem o rearwardly to operate the shell-extractorf by the hereinafter- (No modul.)

described devices, connected with and operated by swinging the partA and cheek-pieces c a' in connection with the joint parts c c', and by the same action to become disconnected from said devices, leaving it free to rotate on thejoint-pin, and let the usual spring on the extractor-stem return the extractor j' against the end of the cylinder B, and swing-arm s ol' the disk o back to its starting-point, or suhstantially that shown in Fig. l.

A pawl, a, a somewhat enlarged view ol'l which is shown in Fig. 2, is adapted to lit. into the slot d in the cheek-piece c, as seen in Fig. 1, the post i of the pawl entering the above-named hole at 8, Fig. 2, and passing` nearly through the part A. rlhe spring m is then placedin the aforesaid countcrbored portion of said hole and on the post 4, and the y hollow screw il is placed on the end of said post, and enters said hole against the end of i the spring, compressing the latter between the screw and the before-mentioned shoulder in the hole, and thereby the pawl ais held in the slot d by the force of said spring. Fig. 3 shows the end of the screw y ou the opposite side of the part A, Fig. 2, projecting a little beyond the surface of said part. By pressing on the end of the screw the pawl w is moved outwardlyin slot d. The pawl n has a short arm or pin, 5, thereon, and an inclined under face, 3, just back of said arm, and when the parts are assembled, as in Fig. l, the said inclined part of the pawl reaches into the curved slot 1o ofthe joint part c, and the arm 5 extends beyond the latter and engages alternately with the slots e c' of t-he disk o, as follows:

The cylinder may be swung to about the position away from the recoil-plate shown in Fig. 1 before the arm e of the disk t will strike the end of the extractor-stem o, the arm 5 of the pawl moving from the left to the right hand end of the slot c' during said swinging movement, and then engaging with the end of said groove it causes the said disk to swing with the cheek-pieces au. untiltheextractorf has been carried far enough from the end of the cylinder, and at this point in its movement the inclined face 3 of the pawl is brought against the end l0 of the slot w in the part c, and is thereby lifted so that the arm 5 is disengaged from the said end of slot e', and the spring-actuated ejector stem drives against arm z, rotating disk e and bringing the groove e therein under the arm 5.

Vhen the frame is swung back toward a closed position with the cylinder, the end ot' groove w passes from under the inclined part 3 of the pawl, or vice versa, letting arin 5 thereon drop into groove e in the disk, and following the latter the end of the arm encounters the inclined end x of said slot, and the pawl is thereby lifted and arm 5 rides over the bridge between slots e e', and drops again into thelatter, moving to the place ofst-arti ng when the arm is closed.

Vhat I claim as my invention, is-

1. In a revolving tire-arm, the combination, with the barrel and framejoint thereof, of an extractor-disk located in said `joint having an arm thereon extending to the extractor-stem and two curved slots therein, a transverselymoving spring-actuated pawl located inthe joint part of the frame, having a post thereon extending through the latter, and an arm thereon engaging with slots in said disk, and an inclined part engaging with the end of a curved slot in' one of the joint parts ofthe barrel, substantially as set forth.

2. In a revolving {ire-arm, the combination, with the extractor-stem andthe joint parts c c ot' the barrel, said part c having a curved slot therein, of the disk e, having the slots e e and the arm z thereon, the spring-actuated pawl n, having the arm 5 and the incline 8, and the part A ot' the frame,having the cheek-piece a thereon perforated and grooved to receive said pawl, substantially as set forth.

3. VIn eombinatiomthe frame part A, having the-cheek-pieces a a', the pawl a, located in said cheek-piece a, spring m, the disk Q2, located between the joint part-s c c', and provided with the arm a, and having the slots e e therein,in which said pawl engages, and thejoint parts c o of the barrel, said part c having a curved slot therein, substantially as set forth.

4. The combination, with the frame and barrel joint parts of a revolving tire-arm and with the extractor-stem thereof, of a disk, sub stantially as described, hung to reciproeally rotate on the joint-pin, and having an arm thereon engaging with said extractor-stem, and apawl, substantially as described, having a movement bodilyin the frame of the arm in a line with the joint -pin and capable, by means substantially as described, ot' automatic engagement with and disengagement from said disk, substantially as set forth.

5.. In combination with the frame and barreljoint parts of a revolving firearm, the eX- tractor-stem o, the disk v, having the slots ee' .t therein, and the arm a, and the pawl n, engaging with the slots in said disk, said pawl having the post et thereon, passing transversely through the frame part A near said joint parts, and capable ot' being acted upon from the outside of said frame part independent of the movement ot the joint parts, substantially as l set forth.
